Hi ,Using FedmIscReader im tring to read / write to the M24LR04-R sector block .Before write operation i need to present the password for each sector.I found Data sheet for M24LR04-R , It has some custom command for present password for M24LR04-R.can you guide me how to sent those command through FedmIscReader or present password through FedmIscReader . because using M24LRxx_Application_Software can able to present the password.In that application , has OBID USB-Driver files . same SDK only im using for my application for comminucating the M24LR04-R.I'm using .net c# for delevelopment

I am designing a system with STM32h753VIT6, with peripherals Ethernet, USB, MicroSD and SPI. 1. How i can program the IC., any previous threads/ref available2.Can I program it with Nucleo H743? if so how?3.Any additional tools/software required.

I need to re-install STM32 CubeMX 4.19 as the latest version 4.24 is not compatible with my existing code base. I inadvertently migrated to 4.24 but need to return to 4.19. Where can I find an archive installer for the older version?

I installed openocd for debugging STM processors according to this blog: https://www.carminenoviello.com/2015/07/13/started-stm32f746g-disco/(Building OpenOCD). It worked fine on my old workstation, as it did on my laptop. On my new workstation I can compile and install openocd. But if I want to start openocd:openocd -f '/path/to/stm32f7discovery.cfg'I get a error:/usr/local/bin/../share/openocd/scripts/target/stm32f7x.cfg:155: Error: invalid command name "stm32f7x.dap"in procedure 'script' at file "embedded:startup.tcl", line 60at file "/home/ARM_LINUX/stlink3/openocd/tcl/board/stm32f7discovery.cfg", line 12at file "/usr/local/bin/../share/openocd/scripts/target/stm32f7x.cfg", line 155Does anyone know how I can fix this?

I have successfully communicated with CR95HF using usb to uart bridge using uart communication. I can read my nfc tag(BL654- type 2) UID using command send from terminal by selecting ISO14443-A protocol.But I have problem with reading data from tag how to read data.For infomation: when i read NFC tag(BL654) from mobile "NFC Tools" andoid application it displays my data wrote on nfc tag.Thanks,Jignesh Patel

I am using the MCU STM32F765VGT6 for my product. The FLASHSIZE_BASE tells me the size of the flash is 1024 kBytes. However, in the IAR workbench linker script (.icf) files, generated through STM32 Cube, the flash address spreads across 2 MBytes. Can someone help me understand his discrepancy?

Hi all,I'm currently working on a bootloader for the STM32L052 MCU. I have a very simple bootlader at this early stage in the development. I have a simple application program that consists of a flashing LED, it compiles to a 4KB .bin file. I then convert this bin file to a uint8_t array to store in the RAM of the bootloader so I can simply test the writing of the program into flash without developing a UART protocol etc. The final version will be using NFC to download the code. I have the bootlader program starting at 0x0800 0000 in the FLASH and the application at 0x0800 F000. The bootloader simply writes the array into this location of memory, then sets the MSP to the first 32bit work of the application address and casts the second word as a function and calls it to launch the application. I have used the AN4657 as reference. However when the application is launched, I get a Hard Fault exception. I think this is due to the way I have the application project setup or perhaps the way I

Hi, is there any way to reset all registers to their default values rather than doing it manually?There is a option call "reboot memory content". However, it seems to be no effect to other registers. So I am not sure what is this thing doing, can any one also tell me what does "reboot memory content" mean?

Hi All,I am using the STM32F103C8?T6 board with I2C PCF8574 with 16x2 1602LCD.When I am initializing the LCD the the backlight automatically goes of.I have tried many times. but result is same.Please advise

hello! as I want to implement TCP/IP and Fatfs based application I have to use HAL library which I'm not very comfortable with. so for other peripherals like USART, SPI and I2C i want to use STD peripheral library which is much easier to understand and implement. or anyone can suggest me an example or reference code using STD peripheral library with TCP/IP stack for stm3220xG eval board.

Hi, i try to produce a PWM to learn but when i try to make this signal on TIM1 channelXn it doesn't matter (for example on PB13 and PA7). On Channel1 all works fine (PC0).What is the difference ?

I've been trying to fins out what exactly this means:"The multi-layer bus matrix allows masters to perform data transfers concurrently as long asthey are addressing different slave modules."(AN4031 Using the STM32F2, STM32F4 and STM32F7 Series DMA controller, 2.1 Multi-layer bus matrix)What I wonder is: are the DMA transfers between different slaves "invisible" to each other - are the transfers truly concurrent? If there is a DMA from, say, internal SRAM to FMC-bus, how does that affect the core/queues?(That is: are the queues in the core-side of the bus matrix?)How about DMA transfer from external SRAM to external SRAM: does the DMA interfere with the core access to internal SRAM/internal FLASH?Can continuous DMA transfer slow down the core altogether, or is the bus matrix a matrix of full buses instead of "arbitration matrix"? And how about the output FIFO of the Chrom-ART?The manuals don't seem to be clear enough for me about that.And why does it say "(Cybercom)" next to my nickname

In the datasheet, it says that LA_TyOff can be eliminated by enabling built-in high pass filter, but for accelerometer, the high pass filter can't be disabled (I assume that the normal mode means high pass filter is enabled, in CTRL_REG7_XM). I had also enabled AFDS, which I think is to use high pass filter mode data, but there are still about 40mg LA_TyOff error in it. So what does it mean that it can be eliminated?

Hi,I am working on USART3 in STM32F407VG Discovery board using stm pheripheral libraries. I am sending a character 'a' but in serial port i am getting data as 3. Please check my main function and kindly help.

I'm trying to build the LwIP_HTTP_Server_Raw demo project for STM32F769-EVAL, which comes with STM32CubeF7 V1.12.0.(project path is .\STM32Cube_FW_F7_V1.12.0\Projects\STM32F769I_EVAL\Applications\LwIP\LwIP_HTTP_Server_Raw)There is a pile of compilation error when building the codes in this directory:../Middlewares/Third_Party/LwIP/test/After checking the source code, it seems some unit test implementation is missing or incomplete.For example, in this file:/Middlewares/Third_Party/LwIP/test/unit/lwip_check.hthe included "check.h" is missing. No such header file exists in the STM32CubeF7 package. Where can I get these source files for the missing unit test?Is anyone encountering the same problem?

Hey everyone,I'm seeing something weird.I've got a working SDIO in 4 bit mode, with dma (FIFO enabled with peripheral flow controller) and using a stm32f722ze.It works perfectly. I can write a large bunch of data to the SDcard relatively quickly even if it isn't aligned with the SDcards block size.This all happens in the main function though.I have a timer running in input capture, it reads in data also using the same DMA (i.e. DMA2) although a different channel, once it has filled the buffer it starts filling a secondary buffer (multi-buffer mode).If I call f_write in the callback for the DMA from the input capture, the sdcard hangs. It gets stuck in either one of these portions :DRESULT SD_read(BYTE lun, BYTE *buff, DWORD sector, UINT count) { DRESULT res = RES_ERROR; ReadStatus = 0; uint32_t timeout; #if (ENABLE_SD_DMA_CACHE_MAINTENANCE == 1) uint32_t alignedAddr; #endif   if(BSP_SD_ReadBlocks_DMA((uint32_t*)buff, (uint32_t) (sector), count) == MSD_OK) { /* Wait that t

Posted on January 26, 2018 at 18:50Hi,I have a problem with the PLLSRC of a STM32F030RC : to obtain 24MHz for the sysclk I have to use PLLMUL @ x6 with HSI (8MHz) but 6x8 = 48MHz ?If I output the sysclk on a MCO pin (with no div) I have actually 24MHz.After use of SystemCoreClockUpdate() from system_stm32f0xx.c the variable SystemCoreClock equals to 48000000 and my call to SysTick_Config(SystemCoreClock/1000) gives a wrong systick frequency ( 2 x too slow, the actuel sysclock is 24000000).In the reference manual RM0360 at the figure 11 I see no div /2 between HSI and PLLSRC for my STM32F030xC.But the behaviour seems like in the figure 10, with a /2 ....Where is the mistake ?ThanksPeter

hello! I've tested the TCP echo server and TCP echo client examples of STM32CubeMX individually and they are working fine. now I want to implement an application where I can use both application simultaneously. So I copied the TCP echo client code files into TCP echo server's code but unfortunately my code keep getting stuck in some ethernet configuration part. are they using some kind of semaphore or something?

Hello, I've brought a new stm3220xG eval board for some development purpose. while going through examples code of STM32CubeMX all of them working fine individually but when I'm trying to use some parameter/functions and files into another code those newly added functions and files isn't working at all. In my project I've added "USART3 printf" example's files and all other initialization related functions into "LWIP TCP/IP ECHO SERVER" as I need a debug port. so does anyone has any idea or knowledge about what possibly could goes wrong? either I'm missing something or improper initialization.?Thanking with regardsAatif shaikh
